### Virtual Method

# Gio ActionGroup get_action_state_hint

since: 2.28

#### Declaration [src]

    GVariant*
    get_action_state_hint (
      GActionGroup* action_group,
      const gchar* action_name
    )

#### Description [src]

Requests a hint about the valid range of values for the state of the named action within `action_group`.

If `NULL` is returned it either means that the action is not stateful or that there is no hint about the valid range of values for the state of the action.

If a `GVariant` array is returned then each item in the array is a possible value for the state. If a `GVariant` pair (ie: two-tuple) is returned then the tuple specifies the inclusive lower and upper bound of valid values for the state.

In any case, the information is merely a hint. It may be possible to have a state value outside of the hinted range and setting a value within the range may fail.

The return value (if non-`NULL`) should be freed with `g_variant_unref()` when it is no longer required.

Available since: 2.28

#### Return value

The state range hint.
